Raised rails have an effect comparable to staggered poles. Thinner vs thicker rails change the inductance and how the magnetic field spreads... EDIT - OK, yet another boringly geeky contribution. Below is the response of pickups played in chords from unfretted strings to 12th fret, direct to...

I suppose that it depends on which Filter'Tron we're talking about. Real FT's (following the original Ray Butts / Gretsch recipe) are low DCR and low inductance humbuckers : around 4k and less than 2H. Their very weak coils are compensated by double thick A5 magnets giving more output and long...

I had forgotten this detail. It makes wrong the advice in my previous post... If two pickups are out of phase magnetically AND electrically, they are RWRP and sound IN phase. To illustrate that, I'll evoke a short-scale Strat that I've here and whose bridge pickup is connected to a phase...

Yes, Artec made/makes OEM pickups for many brands, AFAIK and a bit like Cort factories made/make guitars under other names - Epiphone, etc. And I agree, Artec products are decent to good pickups. Chinese PU's can be even less expensive for a comparable quality but their physical reality...

Not found in my archives the comparison that I searched between covered and uncovered PG1N . I know it's somewhere but I've too many data and not enough brain cells. :-P Now, let's share below the response of a same pickup uncovered VS fitted with a cheap and bad cover (of the same kind than...

At similar weight + dimensions and if magnetized in the same conditions, A5 is less inductive (since the A5 recipe basically contains less iron) and magnetically stronger. Regarding the sound... I totally understand why our fellow members described the typical effect of A3 as they did but...

The higher inductance of a P90 is also due to the area of its coil, BTW, while the coils of the humbucker are less inductive because narrower: even if they were in series with a same polarity, their overall inductance would remain lower than in a P90... This precision making my contribution...

Ok, botched schematic below. It's for a humbucker in parallel and out of phase WITH ITSELF. If the goal is a humbucker in parallel and out of phase WITH ANOTHER PICKUP, see what Artie said and posted (and yes, a 4PDT or two DPDT mini-switches would be required in this case).

Below is my take. Hastily botched schematic. Standard 5 ways switch. One side is used for single coils AND resistors going to ground in parallel with the single coil pickups. The bridge lug of this side is connected to the "common" lug (named here "B 0") of the other side. This other side has...

Since you want the bridge PU always on, its hot output wire can stay permantly connected to the volume pot. The two other pickups can be connected to the switch (whose second side can stay free: it hasn't to be used in this case). See the attached file...

I've found the tracks. They were effectively in my archives, among Audacity files. Agreed, such audio samples are not always meaningful. Anyway, I don't feel authorized to share tracks recorded by someone else. So, I've done something : I've pasted in one screenshot the frequency response...

Below how to wire an ON OFF ON switch to have split / series / split modes...

And to conclude my attempts to help for free albeit apparently without success (except for my own pleasure to share and my self-injonction to answer positively in any situation), below is an illustration of how one can measure flux strenght on a magnet. This one was a rather degaussed A5, if...

... and below is what it would give with a 100k log master tone control changed in a no-load pot... Yes, the curve has 11 steps and no, the red line is not as pointy as in a no-load situation (I've forgotten to reset the simultation accordingly) but "you'll get the picture". ;-) If the sound...

That's why I've suggested to change a low resistance pot in a no-load pot. :-) skelt101 : "Would the placement of the Tone in the signal flow affect anything?" Yes, as mentionned in my previous post, but I'm not sure it's an interesting solution. Let's share below a 5spice sim botched in 5mn...
